What IS good, and how do we determine it?

Because claiming fealty for a religious organization that systematically sheltered child sexual predators doesn't mesh well with the idea that Christianity doesn't condone the torture of children.

Cato, the Catholic religion does not "shelter" these people. The Catholic religion teaches that it is wrong to molest children, and to shelter people who do wrong like this.

Yes, there were people who were Catholic who did horrible things. There were also people who were Catholic who did another horrible thing by covering it up. There are bad people in every group, and Catholics are no different.

Catholicism does not condone any of this behavior. In fact, it vehemently teaches against it.

I agree that there's nothing in Catholicism's catechism that could reasonably be read to support going out and raping children. I think the bigger point is that the organization from which you're drawing the basis of your morals has been shown over and over and over to be engaging in massively hypocritical immoral actions, shielding those who commit them, refusing to discuss the cases with authorities, and refusing to help the victims of said immoral actions. Why would you draw your basis of morality from such an organization? Why not take the base ideas of morality from the catechism and just leave that specific organization? Unless you believe that it's the literal church itself that's more important than the ideas, I don't see why that would be hard.
